I
guess the equivalent for me would be to know Mandarin,
Cantonese, Japanese, Korean, Vietnamese ... and maybe
Sanskrit too - help! ... In fact I'm very impressed
:-) I'm functional in the native languages of most
of the European countries, but they do at least work
on the same basis at English ... I did think of learning
Russian or Arabic
(after
teaching Swedish to a mixed class of Somalis, Kurds
and Eritreans)
as
my next 'world language', but making web-sites took
over instead :-)
I
had a very interesting experience recently with
my 5-year-old nephew Edwin: he has a favourite multimedia
story we play with together on my Mac, and there's
a choice of languages to begin with. It's a matter
of pure routine that I tell him all the choices
rather than just clicking on one for him, and this
day he decided to go for the Japanese version. Of
course he had the pictures to go by, and he knew
the story and all the games, but he listened very
seriously to the whole thing in Japanese, and imitated
the bits which resonated for him in some special
way - great fun :-) And most important, he increased
his awareness that listening to other languages
is something unremarkable...
